Which sleep disorder is most likely to be accompanied by sleepwalking and sleeptalking?

Sleepwalking and sleeptalking are most commonly associated with non-REM sleep arousal disorders, particularly somnambulism. These episodes typically occur during deep sleep, often in the first third of the night. While sleepwalking and sleeptalking can occur independently, they are frequently observed in individuals with a history of sleep disorders, such as obstructive sleep apnea or restless legs syndrome. Factors like stress, sleep deprivation, and certain medications can also exacerbate these behaviors.
